SPECIFICATION forming part of Letters Patent No.622,338, dated April 4, 1899 Application filed January 18, 1898. Serial No. 667,070- (No model.)

To all whom it may concern:

Beit known that I, CARL H. ERICSON, of Boston, (Roxbury,) in thecounty of Suffolk and State'of Massachusetts, have invented certain new and useful Improvements in Mangles, of which the following is a specification.

This invention has relation to inangles, and has for its object to provide certain improvements in the same wherebyfabrics may be ironed more efficiently than heretofore and whereby a superior gloss and finish maybe imparted thereto.

The more specific object of the invention is to provide the mangle with certain improvements whereby the cloth or fabric to be ironed is thoroughly dried or desiccated as it isbeing ironed and polished and is not allowed to leave the mangle in a damp condition.

To these ends the invention consists of a mangle provided with certain features of construction and arrangements of parts,.all as illustrated upon the accompanying drawings and now to be described in detail, and finally pointed out with particularity in the claims.

Referring to the drawings, Figure l represents in side elevation a machine embody- Fig. 2 represents a longitudinal vertical section through the same, the frame not being shown. Fig. 3 represents a longitudinal section through the cylinder and the iron. Fig. i represents a longitudinal section of a devicefor desiccating the fabric. Fig. 5 represents the yielding adjusting devices for the cylinder. I

Referring to the drawings, a indicates the side standards of the frame in which the operative parts are mounted. be of anyshape desired and is provided with journal-bearings for the shafts which impart motion to the cylinder. shaft Z; is mounted in bearings a aon the frame and is provided with belt-pulleys 1) b one of which is fast upon the shaft and the other of which is loose. The shaft is further provided with a worm b inter-meshing with and driving a gear-wheel c on the shaft 0,

ion inter-meshes with and drives a gearwheel d, connected with a cylinder 6. The periphery c of the cylinder is provided with Inwardly-projecting annular flanges e to which are secured the endsof the cylinder, said ends consisting of disks 0 formed on or This frame may The main driving-' This pinsecured to hollow stud-shafts e 6 The gearwhe'el d is secured upon the stud-shaft e so that when the shaft b is rotated the cylinder is slowly rotated. I

The stud-shafts e e are journaled in blocks f, sliding in ways or guides at a on the frame, as shown in Fig. 1, and the said blocks are secured to and rest upon the ends of supporting-bars f, sliding through boxes a as shown in Fig. 1.

' In each box a is placed a spring f", and the supporting-bar f is divided into two portions, each provided witha disk f between which is arranged the spring, so that the cylinder is supported yieldingly to permit the passage of fabrics between it and the iron, as Ishall subsequently describe.

' Upon the ends of the bars f are placed rollers f resting upon cams f secured upon,

a shaft f Likewise secured to the shaft f is a rack-segment f with which a worm f intermeshes, the said worm being upon the end of a shaft f mounted in a bearing a and provided on its end with a hand-wheelf By turning the hand-Wheel f the shaft f may bepartially rotated toraise or lower the cylinder e, the path or plane of movement of the axis of the said cylinder being substantially tangential to the pinion 0 so that the pinion c and gear (Z will not become disengaged.

About the periphery of the cylindrical roll e is placed a thick layer a of felt or equivalent material, and the said periphery e is provided with numerous perforations e for a purpose to be described.

Secured to supports afforded by the frame a is an iron 9, havinga smooth concaveinner face g, concentric with the periphery of the cylinder. The iron is concavo-convex in form and is hollow, being provided with a steaminlet 9 and a steam-outlet 9 whereby it may be heated to the desired temperature.

In front of the cylinder and the iron is a drier or desiccating device which is in shape substantially the half of a cylinder-that is to say, it has a flat top plate h and a curved under plate It and semicircular end walls 71/ The convex under plate h is provided with a smooth outer surface, which surface, together with the concave surface of the iron, forms substantially an ogee or compound curve. The plate h of the desiccating device is pro nected to the fan or blower n.-

fvided with numerous perforations, similar to those in the periphery of the cylinder ordrum 6. v

Passed under the convex surface of the desiccating device and over the drum between it and the iron is an endless band or belt 71, supported by pulleys or rolls 1', i and i, as shown in Figs. 1 and 2. Theroll z" is located near the top of the desic'catin g device, so that the belt or band comes irreontact with the under face of the plate h, and the pulley i is located in position to carry the belt away from the drum as soon as it passes from under the iron 9. 3

The pulleys are all mounted on shafts journaled in bearings on the frame, and in order to adjust the tension of the bolt the bearingblocks t" for the roll or pulley 2' are arranged to slide in' guides 2' and are each internally threaded to receive a screw-bar 1'. bars are provided with bevel-gears i inter meshing with and driven by similar gears i on a transverse shaft 11 A hand-wheel i is secured upon the shaft to turn it and cause the bars i to slide the blocks 2' in their guides.

Placed within the cylinder or drum are two headers jj, both having hnbsj j, supported upon the inwardly-projecting ends of the tubular shafts 6' er and connected by longitudinally-arranged pipes j.

Steam is introduced into one of the headers through the pipe 10 and passes therefrom through the duct it into the opposite header and back through the pipes fij to the exhaust-outlet 70, passing through the tubular shaft e Through the tubular shaft e is introduced a steady stream of air by means of a fan or blower it, connected thereto by a duct 71.

In the desiccating device are two headers Z Z, connected by longitudinally-arranged pipes Z and steam is introduced into the header Z through a steam-inlet pipe l and out from the head er Z by an exhaust-pipe Z. The stream of air is likewise introduced into the desiccating device through the pipe a, con- The fabric to be dried and ironed is pre-' sented to the action of the belt 2 and is carried thereby under the convex plate 72. of the desiccating device and between the cylinder or drum and the ironianjd by'th'time it is" carried out from the latter it is thoroughly dried and is glossed or polished with a superior finish- The fabric being wet is first carried by theldesiccating device, and the air which is forced thereinto is heated by the steam-pipes and passes out through the minute perforations, drying the fabric sulficiently to enable it to be properly ironed and polished when it reaches the next device. The

' remainder of the moisture from the fabric is taken up by the felt uponthe drum, so that the fabric is discharged in a dried condition.

It will be observed that a large portion or a little more than half of the entire The screwperipiiery ,ese

air is forced out through the minute perfora= tions and the felt is thoroughlydried before it again engages the other portion of the fabric.

Owing to the fact that the cylinder is vertically supported on springs, so that the weight of said cylinder is yieldingly supported, it is feasible to obtain almost any amount of pressure on the goods less than the weight of the cylinder. Thus when it is desired to subject some articles to light pres sure the cylinder can be adjusted so that there is but a light spring-pressure against or toward the iron. I

Having thus explained the nature of the invention and described a way of construct ing and using the same, though without attempting'to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is-- 1. A'mangle comprising an iron, a cylinder covered with a suitable elastic material, and having its periphery formed with numerous perforations, mechanism for forcinga stream of air into the cylinder, mechanism in the cylinder for heating the air, and a belt for feeding the fabric to be t'pned.
